...at Rockford, in the county` of Winnebago and State of Illinois, have invent/ed certain 'ment-.and useful Improvements in Vaporizaing-Valves, of which the following'is a deitofsubstantially complete the commingling -.l "on'1vapor-izing- -o fluids passin through the -saxiie," and has for ijt objeetst e production of iclieap, simple and efficient device ofthe elriiid described. 1 l

"ilothis -end xn-'yfinventionconsists in the novelv constructioinI arrangement' and combination of parte herein shown and de-A 'sbrifbedand more particnlarly'pointed out `in -theelainis' In the drawings wherein'like reference chiroters .iilidicate llike `o1: corresponding parts, Figure 1 is e ongitudinal sectional view of my .preferred form of device; Fig. 2 is a. cross-sectional View of the saine taken substantially on line 2 2 of' lFig. 1;' Fig. 3 is a cross-sectional view of the same taken substantially on. line 0L-3;, Fig. l; Fig. 4 is a longitudinal sectional vview of a form of my device; Fig. 5 is a cross-sectional view of the same taken substantially on line 5-5, Fig. 4; Fig. 6 is a longitudinal sectional view of another slightly modified form of my device, and Fig: 7 isfa crosssectional view of the same taken substantially on line 7-7of Fig. 6.

Referring to the drawings, Fig. 1 shows my preferred form of dcv'ice' as applied on the intake port of a gas engine 2, or the like. As shown, a suitable csing member 1, having` an inlet 3 therein is secured to the engine 2 in proximity to the port opening.'

The casing may be secured to the cylinder of the engine in any preferred or suitable manner, preferably by extending the casing as at 25 and securing the same in position by screws or bolts 26 or their equivalents for the purpose. The casing is provided Wit-h a valve seat face 5 on which seats the movable valve member 4, the valve member having an extended stem 7 as shown. The valve member 4 is normally held on the seat 5 by means of the spring 8 or its equiva lent. is a member secured on the stem 7 by ineens of the pin 10 or the like'adapted to-engage the. springe. .As the piston of the engine operates, the iiuids, which have preferably been previously commingled or vaporize in some suitable form of 'carbureter, enter in at inlet 3 and pass Ibetween the valve and its seat into the cylinder, the difference in pressure at opposite sides of the valve caused by the movement-s of the piston controlling the movements of the valve and the passage of iuid therethrough. A"My preferred form of construction is 'arranged to divide the passing uids which are commingled into a plurality of currents "so that they form a number of opposing currents tending to more thoroughly andcompletcly cominingle or vaporize the same. in the Jform shownin Fig. 1 a niember'il provided with a lurality of openings 15 and 15 is arrange on the enlarged portion `110i the valve stem.' The member 12 is arranged. on the portion 11 of the valve stem so as to leave an opening between the merrilber 12 and the valve member 4, as shown .at 16. In the preferred form a shoulder 14 is provided on a valve member 4 and the member 12 arranged thereon and secured by means of a pin 13 or its equivalent for the purpose. As the Huids pass throu h the valve, a portion passes through 15 an a portion through 15 and 16, Where they can meet and pass into the cylinder of the engine. As Ais obvious, member 12 may be made integralrwith'the member 4 if desired, and that there may be any number of openings 15 and 15. The valve member 4 is guided by member 12 contacting with the surfacev 6 of the casing, and a. suitable cap 27 is provided to cover the extended end of the stemfi'l and spring 8.

In'the erm shown in Figs. 4 and 5 the valvefmem'oer 4 is extended as at 4 and arranged .to permit the iiuids to pass throu'gl and through the openings 17 and.

bei-.4 is provided with lugs or extensions 2O arranged to guide the valve membe'i` to its position onv its seat.

Figs. t3 and 7 -also show a modied arrangement in that the easing l is provided with a plurality ot' channels or ducts 21. In this form the mixture is: divided into currents, by the walls Rot the casing as it passes thrbug'h the openings or passageways 9,1 and 23, foru'iing currents as' before de scribed. In this form the valve member 4: is also provided with tht` guidingr lugs 24 arranged to contact with the face 6 of the casing l.

As it is obvious. that in v forni of valve may bc used in combination with other forms of devices rather than a gas engine or the like, I wish to be understood as not limiting the same to that special use, and in the claims, by the word- "i fluid i I wish to be understood as meaning either the uids or the n'iixture ot' the same after it has passed through some preferred form of carburetor.

Having thus described my invention, it is obviousl that various iunnaterial modifications may be made in the form or construction shown without departing from the spirit of my invention, hence I do not wish to be understood as limiting myselfA to the exact torni or construction shown.

"hat I claim and desire to secure by Letters latent is:

1. In a device of the kind described and in combination, a casing provided with an inlet and outlet with a valve seat at said outlet, a movable valve member cooperating with said seat arranged at said outlet, said valve member provided with a member spaced therefrom arranged adjacent thereto on the stem thereof, said member provided with a plurality of perforations therethrough and with a plurality of substantially longitudinal grooves on the exterior1 thereof.

2. In a device of the kind described' and in combination, a casing provided wilth ah itijilet andioutlet with a valve seat at said outl'et, a movable valve member cooperating withr said seat arranged at said vout-let,l said 'valige member provided with a collar arranged on the stem and spaced from the valve member` said collar provided with longitudinal `grooves on the exterior and interior thereof,

means for securing said collar on' the valve stem and means tending to normally resiliently maintaimsaid Vvalve in a closed position. Y

3. In a device of the kind described and in combination, a casi-ng provided with an inlet and outlet', witha valve seat at said i outlet, a movable valve member coperating with said seat arranged at Said outlet, sai valve member provided with a removable collar arranged adjacent thereto on the stem thereof, means for spacing vsaid collar and valve member, said collar provided with longitudinal grooves on the exterior and interior thereof, means for securing said collar on the valve stein and means tending to normally maintain said valve in its closed position.

In testimony whereof, I have hereunto signed my name in the presence 'of two subscribing. witnesses.

'itnesses v '5.
